Scientists from Northern Illinois University and Nasa's Lunar and Planetary Institute in Houston found dozens of valleys, shown in red, after using new software to analyse images of the surface and create the most accurate map to date. The valleys, first spotted in 1971, were caused by a network of rivers more than twice as extensive as previously mapped, pictured right. The new map shows water channels in a belt between the equator and mid-southern latitudes. Experts say this is consistent with heavy rain, and the presence of an ocean covering most of Mars's northern half.
"It would also explain why the valleys become shallower from north to south," said professor Wei Luo. The valley networks show some similarities to river systems on earth, the experts believe.
NASA and their pimp Bill Nelson must be desparate for Obama cash. Next they will claim there are dolphins swimming on oceans on Mars. Give it up. The country is broke. We cannot afford to launch Estes rockets.

That is very cool.
True, we already played golf on the moon, we should let China have Mars all to themselves.
Is it possible that Mars was just like Earth at some time in the past? Could it have an an orbit similar to ours, and over the years drifted away(or forcibly driven away), too far from the Sun to sustain life/atmosphere/water? If the Earth drifted as from the Sun, I could imagine that it would evolve into a planet similar to how Mars is right now after a long period of time.
Are you kidding?
We can’t afford to launch bottle rockets!
Something cause Mars to be in a present state.. That could have happened...
Frack no.. We should be on Mars first...
I suppose an extensive search on Mars would be necessary. Then, we should know much much more about its past. It would be amazing if there were fossils on Mars.
bump :)
Tell 0 he has a private course on the moon with no distractions - keep the no way back as secret as his history.

thanks for the ping
I watched an interview last night with David Satcher, Nicole Stott and Leland Melvin from the International Space Station.
With the Shuttle program winding down, they tried to put a good face on it, but I could almost sense the disappointment in their faces and their sense of loss with America having come so far in space research across the years, and the resignation now that it all seems to be slipping away.
It's all about the mass. Mars is just to tiny to sustain a thick atmosphere (which would keep the water under pressure and thus in liquid form). Plus, it doesn't have a huge, spinning molten iron ball in the middle of it to help with a nice, shielding magnetic field like Earth's (which would keep the Solar wind from blowing away its atmosphere). If we hadn't been hit by that Mars-sized rock a few billion years ago, Earth would probably look a lot like Mars right now.
Not the sun... All of the ancient religions were astral at first and the name associations between pantheon gods and planets are primordial. A group of primitive people devising an astral religion from scratch today would invariably end up worshipping the sun and the moon, but the two chieftain gods of every one of those ancient religions were Jupiter and Saturn, particularly Saturn. Plato consistently refers to antediluvians as "children of Kronos (Saturn)", and Hesiod, Ovid, and others refer to a "golden age" prior to the flood when Kronos/Saturn was "king of heaven". In the same language, the sun is the king of heaven now. The ancients clearly believed that Saturn had been a small star which we, Mars, and Venus orbited, and that the present sun then captured that older system. Youtube searches on "thunderbolts project" turn up some of the details, as will also going over http://www.thunderbolts.info.
It's distance from the sun has nothing to do with not having an atmosphere, it does have one, very thin but still there. The reason it is thin is loss of the liquid core of mars, which in turn caused the loss of the magnetic field around the planet which allowed the solar winds to gradually strip the atmosphere away to the point it is today. The thin atmosphere allowed the water vapor to evaporate into space. If our core ever cools and solidifies, depriving earth of its magnetic field, earth will suffer the same fate.
Thanks for the education! Now that you posted that, I recall seeing what you were talking about on a show regarding Tectonics, and what the planet would be like when our core 'stops'. Mars was their example.
